:wave: Hey,

This PR adds the widening sub instructions. These are similar to the instructions added in #6542. The only difference is that the rules are not commutative so we have slightly fewer of them.

That PR explains how these instructions work in a slightly more detailed way. We have the exact same instructions for both add and sub.
